Definitions
- the present invention relates to couplers for drape rods of the type typically found in exhibit booths.
- the present invention relates to an extendable coupler accessory to affix to a coupler, which is affixed to an end of a vertical pipe to allow accessories to be mounted.
- exhibit booths and the like are constructed using a tubular framework supporting drapes as walls and or covers. Many of these booths are constructed using hook-and-slot systems, which utilize upright aluminum poles with slots formed near the top regions thereof for receiving hooks secured to and extending from the ends of horizontally-positioned tubular rods. Draping material is placed over the horizontal rods to form booths or partitions as may be required. Pipe and drape walls traditionally have a “bumpy” appearance due to the height difference of the vertical members in relation to the top of horizontally disposed connecting rods. Additionally, the steel hooks on industry standard horizontal drape rods have a tendency toward “tearing” the aluminum vertical uprights in a “can opener” effect when the steel hooks are inserted in the existing slots in the uprights. Further, industry standard horizontal drape rods require vertical supports on both ends of the drape rods. Past attempts to solve these problems involve proprietary connectors that are not compatible with the standard steel hooks.
- An object of the invention is to enable the industry standard hooks on horizontal rods and other accessories to rest at such a height as to provide uniform appearance to the top of drape walls.
- a further object is to allow a connection adaptor to mount on a pipe or rod vertical end to allow one or more accessory connections to be affixed to the vertical pipe.
- a further object is to allow multiple horizontal rods to be mounted in parallel from a single vertical pipe.
- a further object is to prevent the steel hooks on industry standard horizontal drape rods from “tearing” into the support pipes.
- Yet another object of the invention is to affix accessories for the industry standard hooks to be inserted at a wider angle of insertion and to allow easier connection as compared to the narrow industry standard slots.
- a further object of the invention is to allow an extendable coupler accessory to be affixed to the coupler such that the extendable coupler accessory mounts via a bridge within existing notches or openings of the coupler while still allowing horizontal rods to be attached to the coupler.
- the extendable coupler accessory is configured with an extendable rod that can extend, and retract, horizontally in a cantilever type fashion to function as a horizontal drape rod with a customizable length without the need for vertical pipe supports on opposing ends.
- a still further object of the invention is to accomplish the foregoing objects using industry standard fasteners or hooks.

The extendable coupler accessory has a nested set of rods that are extendable into a horizontal cantilever position by an extension mechanism. The extendable coupler accessory has an adapter with a bridge that engages with the coupler and prevents the cantilevered rods from tipping vertically or twisting horizontally. The extendable coupler accessory when attached to the coupler by the bridge maintains a horizontal cantilever position with an affixed load.
Accordingly, Applicant submits that an abstract in compliance with 37 CFR 1.72(b) has been filed.
Description
- This application claims priority to U.S. Provisional Patent Application No. 63/320,887, filed Mar. 17, 2022, and entitled “Extendable Coupler Accessory.” The entire contents of the above-identified application are hereby fully incorporated herein by reference.
- The present invention relates to couplers for drape rods of the type typically found in exhibit booths. In even greater particularity, the present invention relates to an extendable coupler accessory to affix to a coupler, which is affixed to an end of a vertical pipe to allow accessories to be mounted.
- In the prior art, exhibit booths and the like are constructed using a tubular framework supporting drapes as walls and or covers. Many of these booths are constructed using hook-and-slot systems, which utilize upright aluminum poles with slots formed near the top regions thereof for receiving hooks secured to and extending from the ends of horizontally-positioned tubular rods. Draping material is placed over the horizontal rods to form booths or partitions as may be required. Pipe and drape walls traditionally have a “bumpy” appearance due to the height difference of the vertical members in relation to the top of horizontally disposed connecting rods. Additionally, the steel hooks on industry standard horizontal drape rods have a tendency toward “tearing” the aluminum vertical uprights in a “can opener” effect when the steel hooks are inserted in the existing slots in the uprights. Further, industry standard horizontal drape rods require vertical supports on both ends of the drape rods. Past attempts to solve these problems involve proprietary connectors that are not compatible with the standard steel hooks.
- An object of the invention is to enable the industry standard hooks on horizontal rods and other accessories to rest at such a height as to provide uniform appearance to the top of drape walls. A further object is to allow a connection adaptor to mount on a pipe or rod vertical end to allow one or more accessory connections to be affixed to the vertical pipe. A further object is to allow multiple horizontal rods to be mounted in parallel from a single vertical pipe.
- A further object is to prevent the steel hooks on industry standard horizontal drape rods from “tearing” into the support pipes. Yet another object of the invention is to affix accessories for the industry standard hooks to be inserted at a wider angle of insertion and to allow easier connection as compared to the narrow industry standard slots.
- A further object of the invention is to allow an extendable coupler accessory to be affixed to the coupler such that the extendable coupler accessory mounts via a bridge within existing notches or openings of the coupler while still allowing horizontal rods to be attached to the coupler. The extendable coupler accessory is configured with an extendable rod that can extend, and retract, horizontally in a cantilever type fashion to function as a horizontal drape rod with a customizable length without the need for vertical pipe supports on opposing ends. A still further object of the invention is to accomplish the foregoing objects using industry standard fasteners or hooks.
- These and other aspects, objects, features, and advantages of the example embodiments will become apparent to those having ordinary skill in the art upon consideration of the following detailed description of illustrated example embodiments.

extendable coupler accessory 300 to affix to pipe-mountedcouplers 10 in a pipe and drape exhibit booth construction. The example embodiments described herein provide anextendable coupler accessory 300 configured with anextendable rod 35 that can extend, and retract, horizontally in a cantilever type fashion to function as a horizontal drape rod with a customizable length. Theextendable coupler accessory 300 mounts via abridge 34 within existing notches oropenings 15 of thecoupler 10 while still allowinghorizontal rods 22 to be attached to the coupler. The “Pipe and Drape” industry is a subset of exhibition and convention services in which frameworks are constructed from horizontally and vertically disposed members in such a fashion to allow draperies or curtains to hang and create division of space in convention halls or other similar areas by arranging drapery walls and booths. Theextendable coupler accessory 300 is designed to provide an improvement to form and function over the industry standard hook and slot technology yet allowing users of existing systems to continue using their inventory of components. -
FIG. 1 is a perspective view of one embodiment of a pipe-mountedcoupler 10, in accordance with certain examples. Thecoupler 10 is used to construct the aforesaid pipe and drape booths. Because the steel terminal hooks traditionally used on the transverse rods in conventional systems to connect to the vertical member or a wall are used to connect to theinstant coupler 10, the steel hooks are not illustrated.Coupler 10 has abody 11 and anupper region 13. Thebody 11 may be substantially circular. In alternate embodiments, thebody 11 is another shape, such as square, hexagonal, or oblong. Theupper region 13 may be of a similar outside dimension as thebody 11 and/or of similar shape as thebody 11. In an example, theupper region 13 is affixed to thebody 11 or is molded, cast, or otherwise formed as a solitary piece or unit. In an internal portion of thecoupler 10, at least onehollow well 14 opens vertically with at least one lateral notch or opening 15 formed inupper region 13 and designed to accept a terminal hook used on an end of a horizontally placed rod. Thecoupler 10 may include any number ofopenings 15, such as 1, 3, 4, or 8. Examples herein illustrate acoupler 10 that has fouropenings 15 disposed at 90-degree positions on theupper region 13. For example, theopenings 15 are positioned at 3:00, 6:00, 9:00, and 12:00. In examples, one or more of theopenings 15 are replaced by a connection bridge or other connection hardware. - The
hollow well 14 may be an open space surrounded continuously or discontinuously by theupper region 13. Thehollow well 14 is open at a top portion to receive terminal hooks. Thecoupler 10 may be hollow such that theupper region 13 and thebody 11 are formed as hollow rings without a floor. Alternatively, thecoupler 10 may have a floor formed within. - The opening 15 is preferably formed in the
upper region 13 with a wider upper dimension that tapers to anarrower seat 17 at the bottom of opening 15. Theseat 17 is positioned at a height above an internal floor, if present, of thehollow well 14 to allow industry standard terminal hooks to rest on theseat 17 within opening 15 and hollow well 14 such that, when used as a rod and drape booth framework, the drapery walls have a uniform, flat appearance and the hooks are securely retained in theopening 15.Upper region 13 has a thickness atseat 17 that is sufficient to engage and retain the terminal hooks of the horizontal rods. - The top surfaces 18 of the
coupler 10 are preferably rounded but may be beveled or flat. Similarly, the tapering surfaces of opening 15 may be beveled, rounded, or flat. Beveled, rounded, or other surfaces on thetop surfaces 18 and theopening 15 may be used to facilitate the sliding of the terminal hooks into theopening 15. - The
coupler 10 illustrated inFIG. 1 has an affixedbase region 12 on the lower region of thecoupler 10. Thebase region 12 allows thecoupler 10 to be inserted into an opening in the top of a vertical pipe or tube or around the opening. Thebase region 12 may have downwardly openingslots 19 which align with the traditional slots formed in standard vertical members to allow the slots on industry standard poles to remain usable when thecoupler 10 is inserted into a standard support pipe. Theslots 19 may have square, rounded or beveled edges and may include a web of material closing the lower end of the slot. Thebase region 12 may have a lattice or matrix structure to reduce raw material usage, reduce weight, and improve strength. - Preferably,
coupler 10 will be made from durable reinforced polymer material, acrylonitrile butadiene styrene plastic, Delrin, polyurethane, or some other suitable material that has sufficient strength and rigidity to effectuate the connection. -
FIG. 2 is a perspective view of one embodiment of industry standardhorizontal drape rods 22 affixed to the pipe-mountedcoupler 10, in accordance with certain examples.FIG. 2 depictscoupler 10 inserted into an opening in the top of avertical pipe 21.Horizontal rods 22 with terminal hooks 23 are depicted resting onseats 17 withinopenings 15. While twohorizontal rods 22 are depicted, any suitable number ofhorizontal rods 22 may be affixed tocoupler 10 byterminal hooks 23 resting onseats 17 withinopenings 15. -
FIG. 3 is a top perspective view of one embodiment of theextendable coupler accessory 300, in accordance with certain examples. In an example embodiment, and as depicted inFIG. 3 , theextendable coupler accessory 300 comprises anadaptor 31 with abottom opening 32, anupper adapter region 33, and abridge 34 withbridge notches 34 a; and anextendable rod 35 affixed toadapter 31 viaadapter opening 36. Theadaptor 31 is configured to mate with acoupler 10, depicted inFIG. 1 . In an example,coupler 10 affixed to a vertical pipe 21 (as depicted inFIGS. 10-11 ) slides intobottom opening 32 upwardly intoupper adapter region 33 such thatcoupler 10 engages withbridge 34 viabridge notches 34 a. In an example, each end ofbridge 34 comprises one ormore bridge notches 34 a. In an example, eachbridge notch 34 a has an inner portion and an outer portion to mate with an inner surface and an outer surface of the sides of opening 15 of thecoupler 10. Whencoupler 10 slides upward intoupper adapter region 33, each end ofbridge 34 viabridge notches 34 a engages with the sides of opening 15 to secure thecoupler 10 to theadapter 31 and accordingly theextendable coupler accessory 300. In an example,coupler 10 engages withbridge 34 such thatbridge 34 rests uponseats 17 withinopenings 15.Bridge 34 may be of a rectangular shape or any suitable shape such thatadaptor 31 may be engaged with, affixed to, or mated with thecoupler 10. In an example embodiment with theextendable coupler accessory 300 affixed to thecoupler 10,additional openings 15 of thecoupler 10 may be available, as depicted inFIG. 11 . Additionalhorizontal rods 22 may be affixed in theavailable openings 15 of thecoupler 10. - Preferably,
adapter 31 will be made from a durable reinforced polymer material, acrylonitrile butadiene styrene plastic, Delrin, polyurethane, or some other suitable material that has sufficient strength and rigidity to effectuate the connection between acoupler 10 andextendable rod 35. In an example,adapter 31 withbottom opening 32,upper adapter region 33,bridge 34, andadapter opening 36 may be molded, cast, or otherwise formed as a solitary piece or unit. Alternatively,upper adapter region 33 andbridge 34 may be affixed or adhered toadapter 31 by screws, an adhesive, or any other connection method. - In an example embodiment,
extendable rod 35 is affixed toadapter 31 viaadapter opening 36. In an example,extendable rod 35 is affixed toadapter 31 viaadapter opening 36 in a removable configuration. In an example,extendable rod 35 may comprise tabs, buttons, or other compressible mechanisms that latch or otherwise mate with notches or openings withinadapter opening 36. In an alternate example,extendable rod 35 is affixed toadapter 31 viaadapter opening 36 in a permanent or semi-permanent configuration. In an example,extendable rod 35 may be molded, welded, soldered, screwed, riveted, or glued intoadapter opening 36. Any other suitable method to affixextendable rod 35 toadapter 31 viaadapter opening 36 may be used. - In an example embodiment, the
extendable rod 35 may function as a cantilever arm maintaining a substantially horizontal position when in an extended position with an affixed load, such as draperies or curtains that may hang from theextendable rod 35. In an example,extendable rod 35 comprises two or more rods that nest within each other when in a retracted position. In an example, an innermost rod of the two or more rods has smaller cross-sectional dimensions, i.e., a smaller width and height or diameter if circular, relative to a second innermost rod of the two or more rods such that the innermost rod can slide or retract, i.e., nest, into the second innermost rod. Each subsequent rod of the two or more rods has larger cross-sectional dimensions relative to an adjacent inner rod. In an example, as the length ofextendable rod 35 is increased, the cross-sectional dimensions of the rods decrease in a direction extending away fromextendable coupler accessory 300, as depicted inFIG. 12 . In an alternate example, as the length ofextendable rod 35 is increased, the cross-sectional dimensions of the rods increase in a direction extending away fromextendable coupler accessory 300, as depicted inFIG. 14 . In an example, the two or more rods are hollow with cross sections that may be arched, circular, c-shaped, u-shaped, rectangular, or any other suitable cross-sectional shape or configuration. In an example, the two or more rods may each be of an equivalent length. In an example, the two or more rods may be of differing lengths. In an example, a length of the extendable rod may be increased by unnesting the two or more rods. In an example, the length of theextendable rod 35 may be extended to any suitable length using an extension mechanism such as a telescopic mechanism, a screw mechanism, a spring mechanism, a guide cable, or any other suitable extension/retraction mechanism. In an example, each rod of the two or more rods comprises a stopping mechanism such that during extension each rod maintains contact with an adjacent rod relative to the nested configuration. In an example, the stopping mechanism provides strength and rigidity during extension ofextendable rod 35. In an example, the stopping mechanism may be a flange, a ring, a linkage, an interlocking mechanism, a stop on screw threads, or any other suitable stopping mechanism. In an example, theextendable rod 35 may extend 2 feet, 5 feet, 10 feet, 20 feet, or any suitable length. In an example, after extension ofextendable rod 35,extendable rod 35 may return to a retracted position with the two or more rods returning to a nested configuration. In an example, the two or more rods may return to the nested configuration by applying a compressive force to an end rod of the two or more rods of theextended rod 35. In an example, theextendable rod 35 may be retracted by reversing the extension mechanism. - In an example with a
coupler 10 affixed to avertical pipe 21 andcoupler 10 engaged with bridge 34 (as previous described herein), when theextendable rod 35 is in an extended position, i.e., cantilevered, the engagement of thecoupler 10 with thebridge 34 of theextendable coupler accessory 300 makes theextendable rod 35 secure from tipping vertically (i.e.,extendable rod 35 maintains a substantially horizontal position) or twisting horizontally. An industry standard rod would fall if only secured on one side as described herein with the present example. - In an example, the two or more rods of
extendable rod 35 may be made from steel, aluminum, polyvinyl chloride (“PVC”), a durable reinforced polymer material, acrylonitrile butadiene styrene (“ABS”) plastic, Delrin, polyurethane, or any other suitable material that has sufficient strength and rigidity to maintain a substantially horizontal position when in an extended position while bearing the weight of an affixed load, such as the weight of draperies or curtains. -
